TOOLTALK Carbide Burrs Carbide burrs are used for cutting, shaping, grinding and material removal, as well as rounding sharp edges. They are cost effective, long-lasting, and can be used on a variety of materials. Carbide Burrs have different shapes which perform different functions, and have their own specialties - which will be highlighted in this Tool Talk. SINGLE CUT VS. DOUBLE CUT Single Cut - Has one, right-handed spiral flute. Removes material quickly and efficiently. Creates long chips. Designed for cast iron, steel, some copper and brass. Can be used for milling, deburring, and cleaning. Double Cut - Has two flutes cutting across each other, providing rapid stock removal for harder materials. Creates small chips. Less pulling, has better operator control. Best if used on ferrous and non-ferrous materials like: aluminum, soft steel and for all nonmetal materials. Good for fine finishing, cleaning, and smooth finish.
